STOVEPIPE.

SPECIFICATION forming part of Letters Patent No. 559,442, dated May 5,1896.

Serial No. 551,144. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES A. DRUMM, ALEX KRAUS, and HENRY GoEnJEN, ofManitowoc, in the county of Manitowoc and State of WVisconsin, haveinvented a new and useful Improvement in Stovepipes, of which thefollowing is a description, reference being had to the accompanyingdrawings, which are a part of this specification.

0 ur invention has relation to improvements in stovepipes.

The object is to provide, in connection with the sections of astovepipe, an improved construction whereby, after the sections havebeen adjusted to bring the stovepipes to the proper length, saidsections can be securely locked in adjusted position.

W'ith the above primary object in View the invention consists of thedevices and parts or their equivalents, as hereinafter more fully setforth.

Referring to the drawings, Figure l is an elevation of telescopingsections of a stovepipe embodying our invention. Fig. 2 is a transversesection on the line 2 2 of Fig. 1, and Fig. 3 is a detail view of thelocking device.

Like numerals of reference den ote like parts throughout the severalviews.

Referring to the drawings, the numeral 7 indicates an inner tubularsection of pipe, which is provided longitudinally with a rounded bead 8.One end of this bead extends to the usual annular shoulder 9, whichshoulder is located a slight distance from the end of the section, whilethe opposite end of the bead extends to the end of the section.

The numeral 10 indicates the outer tubular section of pipe, which isadapted to receive therein telescopically the upper end of the innersection. This part 10 is likewise provided with a rounded bead 11, theconcave I portion of which being adapted to receive the convex portionof bead 8, whereby the two sections are prevented from turning. Theupper end of bead ll terminates at an annular shoulder 12, somewhatremoved from the upper end of section 10. It is advisable that one endof each of the beads terminates short of the section in order to providefor the succeedin g section which is not provided with a bead fittingaround the end of its adjacent section without any open space beingleft.

. The mechanism for holding the sliding sections to adjusted positionconsists of arms 15 15, pivoted together at the point 16. The inner endof each arm is recessed and abeveled shoulder 17 formed at the inner endof said recess, against which the beveled extremity of the arm bearswhen in the position illustrated in Fig. 2. This device is insertedwithin the sections, and when the arms are spread outwardly by downwardpressure at the center the outer ends of said arms are forced againstopposite points of the inner surface of the inner section 7, therebypressing said section firmly against the outer section to hold saidouter section to adjusted position and the beveled inner ends of thearms forced against the respective beveled shoulders of the recesses.

In the practical application of our invention preferably only two of thesections are constructed as herein shown and described, while the othersections may be secured together in the usual manner. If the outersection 10 constitutes the terminal section of the vertical length, andit is desired to connect to a horizontal branch running to thestovepipehole, it is obvious that the proper adjustment can be mostconveniently and readily secured Without the trouble of cutting lengthsto accurately join the horizontal branch, and when adjusted the partscan be readily locked' in adjusted position. It will be noticed that theinner section is smaller in circumference throughout its entire lengththan the outer section, thus making it possible to secure any desiredextent of adjustment.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

In a stovepipe, the combination, with telescoping sections, of a devicefor holding said sections in adjusted position, the device consistin gof arms, said arms having straight outer ends, and having recessesattheir inner ends, said recesses fitting one within the other, theinner shoulders of the recesses being beveled, and the inner ends of thearms correspondingly beveled, and a pin pivoting the recessed ends ofthe arms together, said arms adapted to be inserted within thetelescoping In testimony whereof we afiix our signa- 1o ends of thesections, and to be straightened tures in presence of two Witnesses. outby pressure, whereby the beveled inner ends of the arms are forcedagainst the re- CHARLES A.
